Emerging inorganic compound thin film photovoltaic materials: Progress, challenges and strategies

Interface engineering of p-n heterojunction for kesterite photovoltaics: A progress review

“…Nevertheless, the present record PCE of CZTSSe is still lower than the physical limit defined by the Shockley-Queisser (S-Q) theory or first-principles calculations [23][24][25]. Large open-circuit voltage deficit (V oc ) (less than 60% of the maximum achievable V ocmax) and relatively low fill factor (FF) (about 70%) are common problems in all reported kesterite solar cells, which is the present bottleneck limiting efficiency [4,5,32,33,6,15,[26][27][28][29][30][31]. The limited V oc and FF in kesterite are likely due to two critical aspects: defect-assisted recombination in bulk and interface induced recombination at the heterojunction [4][5][6][7]34,35].…”

Interface Recombination of Cu2ZnSnS4 Solar Cells Leveraged by High Carrier Density and Interface Defects

“…

Pure-sulfide kesterite Cu 2 ZnSnS 4 (CZTS)-based thin-film solar cell has been emerging as a promising cost-effective thin-film photovoltaic (PV) technology, enjoying its Earth-abundant and ecofriendly constituents, thermodynamically stable structure, combined with the ideal bandgap perfectly matching with solar spectrum, and the compatibility with both rigid and flexible substrates. [1][2][3][4][5][6] These compelling features endow this PV technology huge potential for application of various scenes in the future, including wearable and portable PV power sources, building-integrated PVs (BIPVs) at curved building surfaces, and sustainable power sources for internet of things (IOT). [7,8] Moreover, pure-sulfide CZTS is also one of the most promising candidates as the top cell for silicon-based tandem solar cells, potentially triggering further technological evolution for largescale deployment of PV technologies.

Prospects of Integrated Photovoltaic-Fuel Cell Systems in a Hydrogen Economy: A Comprehensive Review

“…IPVFC systems are multi-component systems with a wide spectrum of manufacturing processes and technologies. Although, diverse applications of IPVFC systems in the coming decades will benefit from the falling price of PV modules, and advanced manufacturing processes for the components [134], the system is currently limited by its manufacturability. Ogbonnaya et al [21] proposed that the manufacturing process of an IPVFC system needs to integrate the voice of the customers to capture requirements based on the application context; whilst adapting the supply chain management to a just-in-time system to reduce inventory cost and lead time since most of the components are costly.…”
